MACHINE FOR EMBOSSINQ- WITHOUT DIES.

Specification of Letters Patent.

Patented Aug. 20, 1918.

Application filed October 10, 1914. Serial No. 866,172.

To all whom it may concern:

Be it known that 1, PAUL NATHAN, a citizen of the United States, residing atNew York, in the county of New York and State of New York, have invented a new and useful Machine for Embossing Without Dies, of which the following is a specification.

This invention relates to a machine designed for the same purpose as the machine set forth in the a plication of Frederick A. Virkus, machine or and method of embossing' without dies, filed January 19, 1914, Serial No.-812 964, but the present machine is not arranged to perform all the functions 16 of the Virkus machine.

The principal objects of this invention are to provide a small and comparatively inexpensive machine for melting and drying the powdered. embossing material on sheets or cards which are fed to it by hand with the powdered material thereon; to regulate the eat and the time during which it is applied in such a way that either a glazed or a dead finish can be'secured with accuracy and um- 26 formity; and to provide several improvements in details of construction as will appear hereinafter.

Reference is to be had to the accompanyin% drawings .in which- 80 igure 1 is a side elevation of a machine constructed in accordance with this invention' Fig. 2 is a longitudinal sectional view of the heating oven showing the conveyers in I5 elevation; v

Fig. 3 is a plan of the electric heating oven with the cover removed;

Fi 4 is an elevation of the switches showin sectricalconnections; and

ig. 5 is a plan showing certain details of construction.

The machine is shown as comprising a main base 10 supporting side frames 22 provided witha sheet guide 11 on which the 46 sheets or cards, previously supplied with the powdered material, are placed. They are depositedone at a time partly on this guide and partly on the endless chainconve er or belt 12. As the sheet guide has raise sides 60 the sheets or cards can-be placed up against 16. For operating the conveyer, belting is vided with ad'usting and lock nuts so that top or bottom of the sheet as may be found necessary in order toget the kind of finish them in such a position that they will be taken up by the conveyer or belt in the proper locatlon thereon and consequently there is no need of any uiding device along the edge of the belt. he endless chain or belt carries the cards or sheets through the oven, which is provided with a cover 13, and drops them into a delivery box '14. This has an adjustable stop 15 to accommodate the different sizes of the paper or cardboard that are to be treated. From this the sheets are removed by hand preferably.

At a. convenient point, preferably below the conveyer, is shown the electric motor provided to drive the shaft 17 from the motor. It will be understood that the sizes of the pulleys can be varied for re lating the speed of the conveyer through t e oven. The'conveyer itself is provided with adjustmg screws 19 so that its tautness can be regulated.

It will be noted that the cover 13 of the oven is provided with a handle 20 by which it can be removed and it is provided with ope'mngs 21 at its ends- Tor receiving the belt. The lower strand of the belt passes between the frames 22 on which the cover rests. It will be seen therefore that this cover can be lifted oif easily for the purpose of inspecting the-ovenproper or'adjusting the parts.

The oven itself is composed of two electrically heated ids 24 and 25, one above the upper stran of the belt, and the other 86 below it. In order that the intensity of heat 1 a plied to the powdered material may be var1ed to any desired degree of nicety, the grids are supported by screws 26 which are prothe grids can e raised 'or lowered to bringthem to any desired distance from the paper being fed through. In this way also, the greatest heat can be applied, either on the desired. These grids may be made inany way usual in the manufacture of electrical ovens and other devices.

For the purposeof regulating the heat electrically and also preventing the heat be ing left on. when'the machine stops, the following electrical connections are provlded.

The current is led from a lamp socket or other source of powerythrough a pair of mains 30 through a rheostat 31 which is of any ordinary construction and which will control the speed, of the motor in a well known way.

Connected with this is a double pole posts-34 of the motor switch to which one of the wires 33 is connected a wire 35 extends to one end of both of the grids. The other ends of the two grids are connected separately by two wires 36 and 37 with binding posts 38 and 39 of the heater switch 40. A third binding post 41 on this switch is provided with a wire 42 which is connected with anotherbinding post 43 of the motor switch, this being the binding post to which one of the wires 33 is connected. The heating switch can be turned to four positions. In one of these it connects the binding posts 38and 4:1 and thus allows the current to flow through the upper grid. When in another position it connects the binding posts 39 and 41 and thus allows the current to flow only through the lower grid. In a third position it: connects both the binding posts 38 and 39 in parallel relation with each other to the binding post 41 and thus allows the current to flow through both grids. In the fourth position it disconnects both thebinding posts 38 and 39 from the binding post 11 and thus cuts 01? all connection through the grids. It will be noticed, however, that in any event no current can flow through either of the grids unless the motor switch is on and the motor is running. Consequently no matter how the heating switch'is connected the turning oil of the motor switch will also turn off the current through the oven.

It will be seen, therefore, that with this construction the cards can be heated either from the top or from the bottom, or both, as conditions may require and that the grids may be set at any desired distance from the work so; as to secure any degree of adjustment of the heating efi'ect. Moreover by means of the rheostat and changes in the ratio of transmisson from the motor to the belt the speed of the belt can be re -lated at will. At the same time the mac ine is of a simple and inexpensive construction and is particularly suitable for use in places where the amount of work is not too great to render hand feeding inadmissible.

Although I have illustrated and described only a single form of the invention, I am aware of the fact that many modifications can be made therein by any erson skilled in the art without departing fi om the scope of the invention as expressed in the claims. Therefore I do not wish to be limited to all the details of construction herein shown and I described, but what I do claim is 1. In a machine for embossing sheets, the comblnation with an endless conveyer, of a 2. In a machine of the character de-.

scribed, the combination of a conveyer for carrying the sheets, and an oven locatedadjacent to the conveyer, said oven comprising heating means above and below the con veyer and a hood adapted to be set down over the same and removable therefrom.

3. In a machine of the character described, the combination of a table, a conveyer above it for carrying the sheets, and an oven located on the table and comprising heating means above and below the conveyer and a hood adapted to be set down over the same on the table and removable therefrom by a direct upward motion.

4. In a machine of the character described, the comolnation with a conveyer for receiving and conveying sheets, a heating device comprising a heatin grid located adjacent to the surface of t e conveyer, and a hood having) openings in its ends extending from the ottom to a position above the conveyer and having a handle by which it can be removed from the conveyer by an upward movement.

5. In a machine of the character described, the combination of a conveyer, an electric motor for operating the conveyer, a heating grid parallel with the surface of the conveyer, a circuit whereby a current is supplied to the motor, and means connected with a part of said motor circuit for supplying current to the grid, whereby when the motor is shut, 01f the current will also be shut ofl' from said grid.

6. In, a machine. of the character described, the combination of a conveyer, an electric motor for operating the same, a pair of heating grids, one above and the other be low the conveyer, means for conducting current to the motor, means for conducting current to said heating grids, and means whereby the current can be conducted through either heating grid or both.
